Gas Boosting Station
Pipelines are used to transport natural gas between production facilities and points of consumption. Boosting stations are installed at intervals along the pipeline to maintain the internal pressure required for a constant flow of gas.
A boosting station includes inlet-separation equipment to remove liquid droplets that may be present in the gas stream, a compression unit to increase the gas pressure, a cooling system, auxiliaries and controls.
The core equipment is the compression unit, of which there are three types:
1. The most common type is a centrifugal compressor driven by a gas turbine. The compressor will have a low compression ratio and large gas flow, and the turbine will use a small portion of the pipeline gas as its fuel. Therefore the combined efficiency of the turbo-compressor unit is of great importance.
2. In populated or highly industrialized areas, compressors are often driven by electric motors in order to meet local emission guidelines. This solution does not consume any of the compressed gas, but instead requires a reliable source of electrical power.
3. For small pipelines, reciprocating compressors are commonly used, driven either by reciprocating gas engines or electric motors.
